buf_block_is_uncompressed(): Check that the pointer is aligned.  Use the
C modulus operator % instead of ut_align_offset(), because sizeof(buf_block_t)
is not guaranteed to be a power of 2.

assert ut_a(entry) instead of playing it safe.

point to a buffer pool chunk that has been released when resizing the
buffer pool.

buf_block_is_uncompressed(): Check that the pointer is aligned.  Thanks
to this check, it is safe to pass an arbitrary pointer as a guess
to buf_page_get_gen().

buf_page_get_release_on_io(): Removed this unused function.

ibuf_build_entry_from_ibuf_rec(): Justify why it is not necessary to
add system columns to the dummy table pointed to by the dummy secondary index.

page_zip_rec_set_deleted(): Add a page_zip_validate() assertion.

Add the transaction's weight to information_schema.innodb_trx table.

inserted, uncommitted clustered index records when determining if a
secondary index record that contains a column prefix of an externally
stored column is referencing the clustered index record.

field_ref_zero[]: A BLOB pointer full of zero, for use in comparisons.

btr_copy_externally_stored_field_prefix(): Assert that the BLOB pointer is set.

row_ext_lookup_ith(), row_ext_lookup(), row_ext_lookup_low(): Document
that field_ref_zero is returned when the BLOB cannot be fetched.

row_ext_lookup_low(): Return field_ref_zero and *len = 0 when the
BLOB pointer is unset.

row_build_index_entry(): Return NULL when a needed BLOB pointer cannot
be dereferenced (row_ext_lookup returns field_ref_zero).  Check the
return value for NULL in callers.

row_vers_impl_x_locked_off_kernel(): Avoid comparisons when
row_build_index_entry() returns NULL.

row_vers_old_has_index_entry(): Ignore records for which
row_build_index_entry() returns NULL.  The entry should never be NULL
in rollback, but it may be NULL in purge.

row_merge_buf_add(): Assert that row_ext_lookup() does not return
field_ref_zero.  The table will be locked during index creation.

btr_cur_optimistic_insert(), pass big_rec to it, so that
the field references of externally stored columns (BLOB pointers)
will not be left uninitialized after a successful optimistic insert.
This bug was spotted by Sunny.

row_upd_index_replace_new_col_vals(): Declare fetch_ext.

row_upd_index_replace_new_col_vals_index_pos(): Add a type conversion
to the initialization expression of fetch_ext, to avoid a warning about
comparison between signed and unsigned.

row_upd_ext_fetch(): New function.

row_upd_index_replace_new_col_vals(),
row_upd_index_replace_new_col_vals_index_pos(): Fetch prefixes of
externally stored columns when they are needed for column prefix
indexes.  For memory allocation, add the parameter ext_heap.  Avoid
repeating the inner loop after finding a  matching upd_field->field_no.

column numbers are relative to the InnoDB table object, or numbers
returned by dict_col_get_no().  This will have to be ensured in

btr_free_externally_stored_field(): Add some page type assertions
that were suggested by Sunny.

Fix the size of the static buffer for lock_table and lock_index.
I was not realizing that NAME_LEN contains the mbmaxlen multiplier and thus
a quote, when converted to 2 quotes, will take 2 bytes while there are 3
bytes reserved.

Add C test for innobase_convert_name() in addition to the mysql-test one.

set the "external storage" flag.  When parsing the undo log, do not
misinterpret a SQL NULL column for externally stored.

These bugs were spotted by Heikki and Sunny.

trx_undo_page_report_modify(): Set the UNIV_EXTERN_STORAGE_FIELD flag
when needed.

trx_undo_rec_get_partial_row(): Check for len == UNIV_SQL_NULL.

Fix a bug where the static buffer for innodb_locks.lock_table may not

Bugfix1: Set innodb_locks.lock_index to NOT NULL.
If a column in INFORMATION_SCHEMA table has the flag
MY_I_S_MAYBE_NULL and it is not explicitly marked as NOT NULL
with the method ::set_notnull() then it is always rendered as
NULL by MySQL.

Bugfix2: Avoid crashes if lock_index is NULL. It is NULL for table
level locks.

Move test that depends on ucs2 to a separate file that is disabled if
ucs2 is not compiled in.

Move common SQL commands to an .inc file.

Synchronize the utf8 and ucs2 tests.

innodb_information_schema.test. Add tests that display most columns from
INFORMATION_SCHEMA.INNODB_LOCKS.  Test that quoting of table names works
and respects SQL_MODE='ANSI_QUOTES'.

innobase_print_identifier(): Remove.

innobase_convert_identifier(): New function,
based on innobase_print_identifier().

innobase_convert_name(): New function, similar to ut_print_namel(), but
using a memory buffer.

ut_print_namel(): Use innobase_convert_name().

fill_innodb_locks_from_cache(): Convert lock_table and lock_index by
calling innobase_convert_name().

Convert INFORMATION_SCHEMA tables' names to upper case so that they are
consistent with other INFORMATION_SCHEMA tables.
